[0002] With the continuous development of urban construction, the stability of high slopes has become increasingly prominent. Traditional slope support methods suffer from poor stability and difficulty in construction. Therefore, the development of a new high-slope anchoring system is of great significance for improving slope stability and safety. Summary of the Invention

[0003] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a high slope anchor frame beam fixing device, the device includes a plurality of anchor rods, frame beams, connecting parts and anti-slip piles, the anchor rods are set in the high slope soil, the frame beams are connected to the anchor rods, the connecting parts are used to fix the frame beams to the anchor rods, and the anti-slip piles are set below the frame beams.

[0004] Based on the above technical solution, anchor rods are set in the high slope soil to form a fixing effect with the soil. The frame beams are connected to the anchor rods to withstand the lateral pressure from the soil. The connecting parts are used to fix the frame beams to the anchor rods. Anti-slip piles are set under the frame beams to enhance the stability of the entire fixing system.

[0005] As an improvement of the present invention, the anchor rods are arranged along the potential sliding surface of the high slope soil, one end of each anchor rod is fixed in the soil, and the other end is connected to the frame beam. The anchor rods include multiple sections of interconnected rods, and each section of the rods is connected by threads. The frame beam is a prestressed concrete beam with prestressed steel bars inside.

[0006] Based on the above technical solution, the potential sliding surface refers to the area where sliding may occur in the slope or soil. In the slope stability analysis, the potential sliding surface usually refers to one or more imaginary sliding surfaces inside the slope. These sliding surfaces are the key areas for slope instability and landslides. Prestressed steel bars are arranged inside the frame beam to improve the overall bearing capacity and deformation resistance of the beam. The frame beam is fixedly connected to the anchor rod unit through a connector to disperse the lateral pressure of the soil. The anchor rod is connected by a thread so that the length of the anchor rod can be adjusted according to the actual soil conditions. The steel bars inside the frame beam and the prestressed steel bars are pre-tensioned by tensioning equipment to generate prestress in the concrete beam, thereby improving the bending and shear resistance of the beam.

[0007] As an improvement of the present invention, an enlarged head is provided at the bottom of the anti-slip pile to increase the contact area between the pile foundation and the soil. The upper end of the anti-slip pile is connected to the frame beam, and the lower end thereof is deeply inserted into the soil.

[0008] Based on the above technical solution, the anti-slip pile is made of high-strength concrete and has an enlarged head at the bottom, which is used to increase the contact area between the pile foundation and the soil and improve the stability of the pile foundation. The upper end of the anti-slip pile is connected to the frame beam, and the lower end is deeply embedded in the soil to form a stable pile foundation support structure.

[0009] As an improvement of the present invention, a two-way locking mechanism is provided on the connecting piece, and the two-way locking mechanism includes a locking block, a fixing bolt, a spring pin, a fastening nut and a guide sleeve.

The spring pin is arranged in the groove of the locking block. The fastening nut is used in conjunction with the fixing bolt. The position of the locking block is adjusted by tightening or loosening the nut. The guide sleeve is arranged on the connecting piece body.

[0010] Based on this technical solution, when the connector is subjected to bidirectional forces, the spring pin provides a certain degree of elasticity, while the fastening nut restricts the movement of the locking block, thus achieving bidirectional locking. To adjust the connector's position, this can be achieved by loosening the fastening nut, repositioning the locking block, and then tightening the nut again. This bidirectional locking mechanism enables the high-slope anchor frame beam fixing system to maintain a stable and reliable connection despite complex geological conditions and environmental fluctuations, thereby ensuring the safety and stability of the entire support structure.

[0011] The locking block is the core component of the bidirectional locking mechanism, located at the center of the connector. It secures and locks other components, such as the spring pin and retaining bolt. The locking block is square or rectangular in shape, with a central through-hole for the retaining bolt. The retaining bolt passes through the central through-hole of the locking block, with its ends fixed between the two components. The retaining bolt secures and locks the other components by tightening the nut and can also be released by loosening the nut. The spring pins are typically located on either side of the locking block, with mounting locations for each spring pin. The spring pins insert into the holes on either side of the locking block and, thanks to the spring force, can be easily inserted and removed, temporarily securing or locking the connection. The retaining nut, used in conjunction with the retaining bolt, adjusts the locking block's position by tightening or loosening the nut, achieving bidirectional locking. The nut is typically located at one end of the retaining bolt, corresponding to the bolt head on the other end. A guide sleeve surrounds the locking block, guiding the insertion of the retaining bolt and spring pin, ensuring accurate and stable installation. The shape and size of the guide sleeve should be compatible with the retaining bolt and spring pin to ensure proper installation on the locking block.

[0013] Based on the above technical solution, the enlarged head of the anti-slip pile is conical or cylindrical, and an annular drainage hole is provided on the periphery of the enlarged head to prevent water pressure accumulation in the soil around the pile foundation.

[0014] As an improvement of the present invention, a seismic isolation structure is further provided at the connection between the anti-slip pile and the frame beam, and the seismic isolation structure includes a seismic isolation layer formed by alternately stacking multiple layers of rubber and steel plates.

[0015] Based on the above technical solution, the seismic isolation bearing formed by alternating multiple layers of rubber and steel plates has a good seismic isolation effect.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the high-slope anchor frame beam fixing system provided by the present invention includes anchor rods, frame beams, connectors and anti-slip piles.

One end of each anchor rod 1 is fixed in the soil, and the other end is connected to the frame beam 2. The anchor rods 1 comprise multiple interconnected rod sections 5, each connected by a thread 6. The frame beam 2 is a prestressed concrete beam with prestressed steel bars 7 internally arranged. A potential sliding surface refers to an area within the slope or soil where sliding may occur. In slope stability analysis, a potential sliding surface typically refers to one or more hypothetical sliding surfaces within the slope, which are key areas for slope instability and landslides. Prestressed steel bars 7 are arranged within the frame beam 2 to enhance the beam's overall load-bearing capacity and resistance to deformation. The frame beam 2 is fixedly connected to the anchor rod 1 unit via connectors 3 to distribute lateral pressure from the soil. The anchor rods 1 are connected via threads 6, allowing their length to be adjusted based on actual soil conditions. The prestressed steel bars 7 within the frame beam 2 are pre-tensioned using a tensioning device to generate prestress in the concrete beam, enhancing its bending and shear resistance.

[0025] As an improvement to this embodiment, each connector 3 is designed with a bidirectional locking mechanism to ensure that the connection between the frame beam 2 and the anchor rod 1 is stable and reliable when the high slope is subjected to dynamic loads.
